Conduit baseboard



April 16, 1935. H. GRIMES CONDUITI BASEBOARD Filed Nov. 8, 1952 Patented Apr. 16, 1935 UNITED STATES PATENT OFFICE- 9 Claims.

This invention relates to a conduit base-board made of sheet metal which is adapted to take the place of wood base-boards on walls and partitions in buildings of all types, but being designed more particularly for oflice buildings constructed of fire-proof materials.

One of the objects of the invention is to provide 7 a base-board which may be stamped from a single piece of sheet metal and which may be attached to'a wall without the use of bolts or screws.

Another object is toprovide abase-board having at the upper edge thereof a depending flange adapted to be inserted into a sheet metal plaster ground, the arrangement being such that the upper portion'of the flange extends above the plaster ground and in abutment with the plaster wall.

With these and other objects in View the invention will be better understood by reference to the accompanying drawing forming 'a part of this specification, in which like characters represent corresponding parts in all the views, and in which: 7

Fig. 1 is a sectional view of my improved baseboard attached to a wall. I

Fig. 2 is a. fragmentary perspective view of the plaster ground."

Fig. 3 is a fragmentary perspective view of the base board.

Fig. 4 is an elevational View of the Supporting hooks attached to a tile wall.

Fig. 5 isa transverse sectional view taken on the line 44 of Fig. 1 with the plaster wall and base-board removed. 7

Fig. 6 is a perspective view of a supporting hook for the plaster ground.

Fig. '7 is a sectional detail view having the plaster wall thereon and using a wood plaster ground.

In the drawing i indicates a tile wall having formed on the outer face thereof grooves 2 which provide spaced ribs 3. The outer wall 4 of the tile has aligned openings 5 formed therein in certain of the grooved portions thereof. 8 shaped round wire hooks 6 are adaptedto be inserted through the openings 5 with the bight portion 1 thereof arranged in the openings 5, and the legs 8 and 9 extending downwardly in abutment with The leg H is flattened presently described. A plaster ground i3 is provided with a plaster supporting channel portion l4 adapted to be supported upon the bight portion I5 of the hooks 6. The leg I6 is curved upwardly and outwardly and then downwardly and inwardly with the outer face I! of the upwardly extending portion in abutment with the inner face of the downwardly extending portion l8 and is adapted to be spaced therefrom'by the leg ll of the hooks 6. The ground is further provided -With an upwardly extending curved portion 19 which normally abuts the outer face of the leg l8 and terminates below the bead 28. It will be noted that with this arrangement the outermost edge of the bead 26 extends beyond the upper edge of the portion I9 and thereby provides a thickness gauge for a plaster wall 2!. It will also be noted in Fig. 4 that the leg 22 of channel I 4 abuts the ribs 3 thereby allowing for only slight dropping of plaster through the grooves 2.

and upward vertically as at 29 with the upper end 39 thereof spaced below'the portion 26 and inwardly of the portion 25. The upper end 30is bent backwardly and downwardly against the outer face of the portion 29 to a point level with the portion 28 to form a facing, and then curved outwardly and downwardly as at 3! to form a shoe molding, and inward horizontally as at 32 to form a supporting flange. The upper end 33 of the portion 24 is bent downward vertically as at 34 in spaced relation with the portion 26. The portion 34 is adapted to be. inserted between the portions l8 and !9 of the ground l3 with the upper portion thereof in abutment with the wall 2!, and supporting flange portion 32 resting upon the floor 35. The vertical portion 21 is adapted to abut the ribs 3with the horizontal portion 28 resting upon I the bight portion I5 of the hooks 6'. The flattened leg I I is adapted to be insertedbetween the portions 29 and 3!, thereby supporting and limiting outward movement of the channel portion 36 formed by the portions 21, 28 and 29. The channel 35 is adapted to receive and support telephone wires or the like 31, and which may be inserted through the opening 31'.

From the foregoing it will be seen that I provide a simple :and inexpensive device which may be expeditiously installed without the use of bolts, screws or the like.

If desired the face plate and shoe mold 3| may be formed of a separate piece and welded to the leg portion 28 of the channel 38 and be formed of heavier and more durable material.

In Fig. 7 is illustrated the employment of a wood plaster-ground 13 which rests upon the bight portion i5 of the hook 6.

It is to be understood that various changes may be made in the device without departing from the spirit of the invention or the appended claims.

Having thus described my invention, what I claim is:
